1.0 INTRODUCTION
This report describes our observations jurisdictional wetlands on or
within 100’ of the 4.50 acre property known as “Cedars at the Highlands”
(Parcel #145750-0110), located off 160th Avenue SE, in the City of
Renton, Washington (the “site”).

The site, located in the SE quarter of Section 14, Township 23 North,
Range 5 East of the W.M., includes a forested area disturbed by past use
as a dirt bike track and storage area under the tree canopy, as well as a
large shop building with associated gravel driveway and parking areas.
The area is abutted by single family parcels to the north and south, and
a new road being constructed along the east. The west side of the site
abuts 160th Avenue SE.
2.0 METHODOLOGY
Ed Sewall of Sewall Wetland Consulting, Inc. inspected the site in March
of 2016. The site was reviewed using methodology described in the
Washington State Wetlands Identification Manual (WADOE, March
1997). This is the methodology currently recognized by the City of Renton
and the State of Washington for wetland determinations and
delineations. The site was also reviewed using the methodology
described in the Corps of Engineers Wetlands Delineation Manual
(Environmental Laboratory, 1987), and the Western Mountains, Valleys
and Coast region Supplement (Version 2.0 ) dated June 24, 2010, as
required by the US Army Corps of Engineers. Soil colors were ident ified
using the 1990 Edited and Revised Edition of the Munsell Soil Color
Charts (Kollmorgen Instruments Corp. 1990).
The Washington State Wetlands Identification and Delineation Manual and
the Corps of Engineers Wetlands Delineation Manual both requires the
use of the three-parameter approach in identifying and delineating
wetlands. A wetland should support a predominance of hydrophytic
vegetation, have hydric soils and display wetland hydrology. To be
considered hydrophytic vegetation, over 50% of the dominant species in
an area must have an indicator status of facultative (FAC), facultative
wetland (FACW), or obligate wetland (OBL), according to the National List
of Plant Species That Occur in Wetlands: Northwest (Region 9) (Reed,
1988). A hydric soil is "a soil that is saturated, flooded, or ponded long
enough during the growing season to develop anaerobic conditions in the
upper part". Anaerobic conditions are indicated in the field by soils with
low chromas (2 or less), as determined by using the Munsell Soil Color
Charts; iron oxide mottles; hydrogen sulfide odor and other indicators.
Generally, wetland hydrology is defined by inundation or saturation to
Harbour – Madison/#16-152

the surface for a consecutive period of 12.5% or greater of the growing
season. Areas that contain indicators of wetland hydrology between 5%-
12.5% of the growing season may or may not be wetlands depending
upon other indicators. Field indicators include visual observation of soil
inundation, saturation, oxidized rhizospheres, water marks on trees or
other fixed objects, drift lines, etc. Under normal circumstances,
indicators of all three parameters will be present in wetland areas.
3.0 OBSERVATIONS
3.1 Existing Site Documentation
Prior to visiting the site a review of several natural resourc e inventory
maps was conducted. Resources reviewed included the NRCS Soils
Survey, the National Wetlands Inventory, and the WDNR Fpars Water
Typing Maps.
3.1.1 NRCS Online Soil Mapper Soil Survey
The site is mapped as containing Alderwood gravelly sandy loam (Map
unit AgC). Alderwood soils are not considered "hydric" or wetland soils
according to the publication Hydric Soils of the United States (USDA
NTCHS Pub No.1491, 1991).
Above: NRCS Soil map of the site.

3.1.2 National Wetlands Inventory
According to the National Wetlands Inventory for the site, there are no
wetlands on or near the site.

3.1.3 WDFW Priority Habitats
A review of the WDFW Priority Habitat map covering the site revealed no
priority habitats or species within 1,000’ of the site.

3.1.4 WDNR Fpars Water Type Mapping
According to the WDNR Water Type Map for the site, there are no
mapped streams or waters on the site.
Above: WDNR Fpars Water Type Map
3.1.5 City of Renton Stream Map
The City of Renton Stream map has no streams mapped on or near the
site. The closest streams are several Class 4 streams mapped
approximately 4,000’ east of the site.

3.1.6 Mindys Place Wetland Study
Sewall wetland Consulting conducted a study of the parcel immediately
to the north of the site referred to as Mindy’s Place. This site was found
to what at the time under old Code was classified as a Class 4 water with
an associated 35’ buffer. This stream exited the Mindy’s Place site at its
southeast corner and continued onto the site.
3.2 Field Observations
3.2.1 Uplands
As previously described, the site contains a gravel driveway accessing a
large shop building on the site. There is also a small outbuilding east of
the site, as well as large gravel parking areas, as well as scattered
vehicles. The western portion of the site contains an open canopy
forested area with 20-30 year old cottonwood trees with a sparse to bare
understory. Scattered patches of Himalayan blackberry, indian plum,
hazelnut, vine maple and stinging nettle are also present throughout the
site. This area has been significantly disturbed in the past and most soil
pits excavated within this area revealed a mix of fill and natural soils
mixed. The drainage ditch along the east side of 160th drains through a
culvert passing through the site to the east.
Soil pits excavated in the upland areas revealed disturbed gravelly loam
as well as a high chroma, dry gravelly loam soil.
3.2.2 Wetlands
No areas meeting wetland criteria were found on the site.
3.2.3 Waters
As previously stated, a small ephemeral stream channel passes through
the northeast corner of the site. The ordinary high water mark of this
stream was flagged with white and blue flagging labeled OHWMW1-W6.
As defined in RMC 4.50.G7.a, this stream best meets the criteria of a
Type Ns water due to its intermittent flow and lack of fish use.

March 28, 2017
Page 7
Per Renton Code section 4.50.G.2, Type Ns streams have a 50’ buffer
measured from the OHWM as well as a 15’ BSBL measured from the edge
of the buffer to any structure.
4.0 Proposed Project
The proposed project is the construction of a 14 lot plat with associated
infrastructure. No impacts to the Type Ns stream or its buffer are
proposed.
